T 0 all whom it may concern:

Be it known that I, JOHN D. BOYLE, a subject of the King of Great -Britain, and a resident of Pelham Manor, county of Westchester, and State of New York, have invented certain new and useful Improvements in Powder Packages, of which the following is a specification.

This invention relates to the packaging and dispensing of pulverulent material such as toilet powders.

Some of the more important objects of the invention are to provide an Original form of package which will be neat and attractive in appearance, simple and inexpensive to manufacture and which will have incorporated within it practical and efiective means for dispensing the powder in a speci-- fied quantity, and regardless of the position in which the box is held.

Other objects and the various novel features which make the attainment of such' objects possible, will appear as the spec1fica-.

tion proceeds.

111 the drawing accompanyin and forming part of this specification have illustrated but two of the many possible forms the invention may take and therefore wish it understood that the structure may modified and changed in various respects without departure from the true spirit and scope of the invention.

Figure 1 in the drawing referred to is a perspective view of the package embodied in pyramidal form and illustrating the method of its use.

Figure 2 is a broken front view of the package, partly in section.

Figure 3 is a substantially central vertical sectional view of the same.

Figure 4 is a horizontal section on substantially the plane of line 4.-4 of Figure 2.

Figure 51 is a central sectional view of a form of the'invention in which the container is of cylindrical shape.

In a preferred form of the invention the container is of substantially pyramidal shape having a flat rectangular bottom from which rise the front and back sides 6, 7 and the narrower ends 8, 9, converging to a point having a discharge opening 10.

The sides 6, 7 are flexible and elastic so that they may be compressed or pinched together, as indicated in Figure 1, and the ends 8, 9 are relatively rigid and stiff to brace the compressible sides and limit the extent of their compression. These results may be effected by making the box of relatively stiff cardboard, the wider expanse ,of the sides providing sufficient flexibility for the compression movements and the smaller expanse of the ends providing the stiffness and rigidity necessary for bracing the sides and limiting the compressive movements. The folding of the cardboard at the bottom to close the box provides the rigidity and strength for holding the sides and ends rigidly connected and also forms a rela tively broad fiat supporting base for the package.

The powder is discharged from the box in the form of pufl'sor clouds by means of a tube 11 secured in the mouth of the outlet and extending downthrough the body of the powder to a point close to the bottom of the box. This tube in a preferred form of the invention is made of paper coiled or A rolled into tubular shape, as indicated, and impregnated or coated with wax or like material to'make it smooth and impervious. This prevents the powder from adhering to the tube and causes it to discharge smoothly and evenly with but a slight pressure on the sides of the box.

This discharge tube, as in my former patent, may have an enlargement or collecting funnel at the lower end of the same, such as I have indicated at 12, by somewhat enlarging-the end of the tube, or as shown at 13, a flap may be extended from one of the sides of the box and folded back thereinto toprovide a collection chamber or funnel 14 about the end of the tube. This flap is indicated as being simply bent up into the body of the container and as having an extension 15 projecting at an angle downwardly from the innermost portion of the flap to the bottom of the box, the lower.

end of the tube being shown as fitting in a slot 16 formed at the junction of this re- 1t lurn flap with the main body portion of the ap.

The powder can enter this pocket or 001- lecting chamber by a slot 17 provided in the flap 13 and also by 'way of the slot 16 which is provided for the reception of the lower end of the tube. usually secured in the mouth of the outlet by forcing the tube thereinto until it flattens out and conforms more or less to the rectangular cross section of the box at this point, substantially as indicated at 18. An

adhesive or holding agent may be employed to permanently secure the thus conformed end of the tube in place, as indicated at 19.

The discharge tube is usually inserted while the box is'held in inverted relation and the bottom of the box is'open. After the tube is secured in place the box is charged with powder and the flap which provides the collecting chamber 18 forced inward and about the lower end of the tube, after which the bottom flaps are closed. A wrapper 20 may then be applied about the box to seal the bottom air-tight, and to $105 6 ns provides an air-tight container protecting the contents from moisture and preventing the 10$ of fragrance or other qualities. The contents is available at any time upon simply clipping the tip of the wrapper to uncover the end of the discharge tube and then by squeezing the sides of the box the material may be ejected in cloud-like form upwardly, downwardly or in any direction. The substantially rigid end walls brace the flexible side walls and operate in efi'ect to limit the amount of compressive force which can be applied thereto. By limiting the pressure which can be applied only a proper amount of powder will be expelled.

1n the form of the device disclosed in Figure 5 the container 21 is of cylindrical form, the side walls thereof being sufficiently elastic to provide the necessary pumping action, and the top and bottom being sufficiently rigid to limit the pumping action. The discharge tube in this case is shown as centered in the top of the box, being he d therein by suitable adhesive, as before. and having its mouth sealed by a paster or wrapper 22.

in adu t-l lo i to its simplicity and circaness both at this improved package have the advantage that the boxes can be made up, filled, weighed and sealed on more or less automatic and standard machines.

What I claim is:

1. An original powder package comprising a substantially pyramidal container of relatively stifi but flexible springy material having a rigid flat bottom for supporting the package upright, substantially rigid end walls and compressible side walls tapering to the peak of the pyramid, the substantially rigid end walls bracing and limiting the compressive movements of the side walls, the container thus constructed having a discharge throat in the peak of the same, a discharge tube extending t'rom near the bottom of the container and having its upper end secured in the discharge throat, a flap in the bottom of the container bent up about the lower end of the discharge tube.

2. The structure of claim 1 in which the tube is of waxed paper to reduce friction and-facilitate free, smooth discharge of the contents.

3. An original powder package comprising a container having slightly compressible side walls rigidly braced to prevent collapse or buckling of the container, a discharge tube of smooth moisture-proof waxed paper extending from near the bottom of the container through the top thereof.

4. In a powder package, a container having slightly compressible side walls rigidly braced apart by end walls, a discharge tube extending 't'ronrn'ear the bottom of the container to the top thereot and a flap in the bottom of the container bent to form a funnel or collection chamber about the lower end of the tube.

in witness whereof, I have hereunto setmy hand this 22nd day of June, i922.
